5 Causes of a Transmission Fluid Leak

5 causes of a transmission fluid leak

Have you ever wondered why a puddle of red fluid always seems to appear under your vehicle magically? There’s a big problem if you have noticed similar stains on your garage floor or driveway or keep refilling your transmission fluid. You have a transmission fluid leak that needs urgent attention. Ignore it, and you may be headed for a complete transmission failure!

The Importance of Transmission Fluid

The transmission fluid, also referred to as ‘transmission oil,’ is the lifeblood of your vehicle transmission. Its reddish color makes it relatively easy to identify. The primary job of the transmission fluid is to lubricate and protect transmission components efficiently. 

If you have low transmission fluid levels or a leak, it may significantly affect the transmission’s overall performance. If ignored for a long time, it could cause crucial damage to those components. You will spend lots of money fixing the leak and then replacing the transmission oil.

What Causes a Transmission Fluid Leak?

A leaky transmission may be caused by a critical or minor issue you can tackle, either on your own or with the help of a professional auto mechanic. Whichever one it is, joking around with a problematic transmission is a mistake you should never make.

Here are the top common causes of leaky vehicle transmission:

1. Broken Seals

Automatic transmissions efficiently sustain hydraulic pressure via several different transmission seals. But over time, these seals get worn out and crack. This often occurs when the seals are constantly exposed to heat or high temperatures. It could also occur when too much transmission fluid floats within the system.

Therefore, if a transmission leak occurs due to broken seals, you may need to have several areas checked by an auto specialist. However, in most cases, mechanics find leaky seals in the output shaft or input shaft.

The mechanic may need to also examine the following transmission-reliant components:

  • The sensors
  • The transmission pan
  • The driveshaft
  • The shifter housing seal
  • The speedometer input seal
  • The plug seals
  • The tail housing seal
  • The valve body

2. Drain Plug/Transmission Pan

The drain plug or transmission pan is a durable component that will experience wear and tear over time. It is highly vulnerable to damage as it takes several daily hits from debris and loose rocks on the road while driving.

A transmission leak occurs when the transmission pan becomes punctured. It may also occur due to loose bolts or drain plugs. A leak will occur quickly if you drive on rough terrain and a big rock – or some other hard object – hits the transmission pan. You will usually notice this almost immediately, and your transmission starts losing fluid quickly.

It may take a while to notice smaller punctures or holes in your transmission pan. Leakage may occur if the bolt or drain plug is over-tightened until it strips or if they are not tightened enough. 

This problem usually occurs almost as soon as you change the transmission fluid. So, ensure the mechanic that will work on your vehicle is a professional. They will know the exact force to apply or use when tightening bolts, etc.

3. Transmission Pan Gasket Fails

The transmission pan gasket is a vital component of the transmission system. The gasket may get damaged due to a wrong alignment during a previous installation. It could also be damaged if exposed to high temperatures constantly or as a result of poor construction/manufacturing. Whatever the case, the outcome is a transmission that leaks its lifeblood.

The transmission pan gasket is affordable and easy to replace. Get a professional auto mechanic to replace the pan gasket as soon as possible. If you delay a little longer, more severe issues will crop up, requiring you to spend more resources to fix them.

4. Cracked Fluid Line

Most fluid lines of vehicle transmission are made from durable aluminum or steel. However, they’re prone to damage due to heat exposure or road debris. These could cause the fluid line to crack or even break completely, resulting in transmission fluid leakages.

5. Leakage of Torque Converter

The transmission fluid finds its way into the whole system via the torque converter. However, transmission fluid will leak if there is a crack anywhere on the body of the torque pump or the needle bearings are severely damaged.

This is a big problem and a complicated fix. Therefore, take your vehicle to the local mechanic. The only option, in this case, is to replace the torque converter.

How to Maintain Your Vehicle’s Transmission

Transmission issues are usually bothersome and expensive compared to other types of vehicle repairs. This is why knowing how best to take care of your vehicle’s transmission is vital.

Check Transmission Fluid Levels

Every now and then, check the levels of your transmission fluid as well as its overall condition. Follow the vehicle manufacturer’s procedures in the owner’s manual before inspecting the dipstick. In some instances, you can only make these checks when a vehicle’s engine is running while some other vehicles’ engines must be off.

A Sweet Smell with Reddish Color is Good

Good transmission fluid should have a sweet smell and a reddish or vibrant shade of pink. However, it is not uncommon for the transmission fluids in some vehicles from specific manufacturers to be of a different color.

Get a Transmission Flush Every 30,000 Miles

If you need to top up the transmission fluid level, ensure you use the right and perfect kind, as recommended by your vehicle’s manufacturer. Create time for regular transmission flushes. Experts suggest performing transmission flushes every 30,000 miles.

Don’t Forget to Service the Coolant System

Make sure to service your coolant system from time to time. This ensures the proper functioning of your entire cooling system, which helps to cool the transmission fluid.

Opt for Certified Transmission Repair Annually

Another excellent maintenance habit you should learn is having a certified transmission repair expert look over your transmission. You can have this inspection performed at least once per annum. This is the easiest way to discover any hidden or unnoticeable transmission issues that can be nipped in the bud before it becomes serious and will cost you lots of money to fix.

Fixing a Transmission Fluid Leak to Prevent Failure

There you have it: the most common causes of transmission fluid leaks. Fooling around with a problematic transmission is a big mistake. It could result in complete transmission failure, which would cost you a lot of money to fix.

When you notice a transmission leak, find your way to the nearest auto mechanic shop to have your vehicle checked and fixed immediately.

Fixing a Transmission: 6 Benefits of Hiring an Expert

Fixing a transmission: 6 benefits of hiring an expert

As a vehicle owner, the ability to do small maintenance tasks can save you a few dollars here and there. Installing a new car battery, adding oil, or screwing on an air filter are small tasks most car owners can do. However, it is another ball game when it comes to fixing a transmission and any parts associated with it. You’ll need the professional assistance of an expert.

Many car owners make the mistake of visiting standard auto mechanics or service centers. Although the average mechanic can easily handle simple transmission repairs, they don’t have the requisite tools for high-tech diagnosis of transmission problems.

If your transmission has a more serious issue, a standard auto repair mechanic may not be capable of handling it. You will still need to find a transmission specialist who knows the ins and outs of vehicle transmissions and can expertly and accurately diagnose its problems.

This will cost you 2x more money and precious time, which you should not trade for anything. In order to avoid these, you should always opt for a specialist anytime you have transmission problems.

The Advantages of Hiring an Expert for Fixing a Transmission

If you are still not too convinced about the importance of having a specialist work on your faulty transmission, these benefits would:

1. Repair Complexity

Transmission is one of the most integral and complex pieces of a vehicle’s system. Unlike the punctured car tire you can easily change or a small hose you can patch without breaking a sweat, transmission issues are usually complicated.

Transmissions are made up of multiple components and pieces, and each of these parts can easily experience problems. Moreover, transmission designs vary by model and make. 

Only a well-trained and experienced professional can swiftly give an accurate diagnosis of any transmission problem. Experts use industry-specific computer programs to tap into the computer system of a modern vehicle in search of accurate diagnoses of car issues.

Professional mechanics know how to run these computer programs efficiently. They also possess the necessary tools – which often reflect the complexity of transmission repairs – required to fix faulty transmissions.

2. Warranty Protection

At least two iron-clad warranties become functional here. First, having an expert perform transmission repairs helps protect your vehicle’s warranty. Secondly, most highly trained and experienced specialists offer their own warranties on transmission repairs.

This implies that in the rare or uncommon case the expert misses something during transmission repairs, you will be protected from paying out of your pocket for additional repairs.

Ensure you make inquiries, read, and fully understand whatever extended manufacturer warranty the mechanic offers before they start working on your vehicle.

3. Cost-Efficient

Fixing your transmission can be expensive, especially if you don’t have the ideal tools. You should not engage in such activity without the necessary repair components and tools.

Hiring an expert is the most affordable choice since they have all the right tools and repair components.

4. Eliminate the Stress of Repairs

It doesn’t even matter if you are an experienced Do-It-Yourself mechanic. The pressure of getting your vehicle running again in top-notch condition will subject you to a lot of stress.

For instance, you will spend lots of money – and time – tracking down the appropriate tools for fixing the defective transmission. Taking down, repairing, and re-installing a transmission is not a one-man job, i.e., you will require at least another pair of hands. You will need to call up a couple of your friends who also have time to kill and are willing to assist you in your repair quest.

As you can already see, the stress of doing it yourself is not worth it. The best way is to get an expert to check the transmission, give accurate diagnoses, and take steps to fix the issues for good.

5. Peace of Mind

Having an expert work on your vehicle’s transmission gives profound peace of mind. Maintaining a healthy transmission or repairing a faulty one will get you through adverse conditions such as off-road terrains, bad weather, etc.

A professional mechanic can easily detect the daily wear-and-tear issues transmissions undergo. They can fix these issues before they escalate into something significant and expensive.

6. Specialization

A car transmission expert is not the usual Jack-of-all-trades mechanic in many cases. An expert has undergone the proper training and is certified and knowledgeable at efficiently diagnosing high-tech transmission issues, especially in heavy-duty vehicles like trucks and vans.

They also have a better experience as understanding particular causes of transmission issues in specific vehicles is their forte. This is what you need if you value your time and money.

Quick Tips to Keep Your Vehicle Transmission Healthy

Keeping your vehicle transmission in tip-top shape on a daily basis is highly essential. Follow these quick tips that will help ensure your transmission remains healthy at all times:

Transmission Flushes

It is vital to change your fluids from to time. Having low fluids and not doing anything about it is a recipe for future transmission issues or difficulties.

Always address low transmission fluid as soon and as soon as possible. Avoid driving your vehicle when its transmission fluid is low or below the recommended level.

Replacing a seal is less expensive, can easily fix the problem, and save you lots of your hard-earned cash on repairs down the road.

Do Not Ride the Brake

You force your transmission to work even harder whenever you drive with your foot heavy on the brake pedal. Avoid doing this as much as possible in order to prevent transmission problems.

Use the emergency brake each time you park your vehicle on an incline. This helps to minimize stress on the parking lineage.

Always Stop Your Vehicle Completely Before Shifting from Reverse to Drive

Anytime you are in reverse, such as backing out of a particular parking spot, etc., ensure you stop your vehicle completely before shifting into Drive.

You must have experienced the dreaded ‘engine drop’ when you don’t stop before shifting gears. When you stop completely before shifting gears, it helps prevent the transmission from unwarranted strain.

Leave it to the Professionals

The benefits of hiring an expert for fixing a transmission cannot be overstated. You may be able to do minor fixes like changing your car tires, installing a vehicle battery, or even screwing on an air filter.

But when it comes to repairing a faulty transmission, leave it to the professionals. You will have profound peace of mind, protect your warranty, and have a specialist handle every complex issue on your behalf.

Replacing a Transmission: Is it Worth it?

Replacing a transmission: Is it worth it?

Experiencing transmission issues is inevitable as long as you are an active vehicle owner and user. However, the real challenge that you could face is making up your mind about repairing or replacing a transmission.

Each time your vehicle transmission shifts, gears, bands, and clutches within the mechanical system must apply and release so that the shift will occur. This strain occurs regularly and over time, resulting in extensive wear. This could, in turn, lead to some catastrophic or major transmission failure.

Repairing faulty transmissions is one of the costliest ventures you could make on your vehicle. This is why you need to ask yourself these important questions: “Is repairing the transmission worth it, or should you replace it? Is replacing the transmission even worth it?”

The truth is that there is no one straight or one-size-fits-all answer to this question. However, repairing the transmission is a better and less expensive option unless your vehicle’s transmission breaks down prematurely.

When a vehicle attains a particular mileage count and age, it doesn’t really make much sense to get a new transmission. This is because the latter will be much more than the vehicle’s current worth.

A transmission breakdown in a relatively new vehicle will require immediate fixing. If you own a vintage automobile, repairing any transmission issues is the best bet.

Factors That Influence the Costs of Replacing a Transmission

The transmission of a modern vehicle is not one solid piece but a jumble of several moving parts. This is the primary reason fixing a vehicle’s transmission is more expensive.

Other factors that influence the overall costs of replacing a transmission include:

  • The age of the vehicle
  • The car manufacturer
  • Is the transmission manual or automatic?
  • Where are you getting the repairs to your vehicle?
  • Who have you quoted to perform the repairs on your vehicle?

These factors will influence your decision to replace or repair your transmission.

1. What is the current worth of your vehicle?

As mentioned briefly earlier, before you decide whether to replace your transmission, compare the cost of replacing it to the total (current) worth of the vehicle.

A brand-new transmission costs anything from $1,000 to $7,000+. Therefore, if the current worth of your vehicle ranges from $8,000 to $10,000, replacing the transmission will be worth it.

But if your vehicle is under or within the transmission range, it won’t make much sense to replace its transmission. The best way out is to scrap and sell off your vehicle in order to get a new car.

Moreover, the overall cost of replacing a vehicle’s transmission depends primarily on the type, model, or make you own. For instance, replacing the transmission of an exotic or luxury vehicle will cost you $10,000 or more. But that of a truck will cost up to $3,000, while a sedan’s new transmission does not usually cost more than $2,800.

2. How Much Will It Cost to Repair a Damaged Transmission?

You should get a well-detailed quote from an experienced mechanic. The quote should highlight how much it will cost you to repair the faulty transmission. If only the transmission troubles your vehicle – and no other component is involved – the quote should mention this.

Get the mechanic to perform an extensive examination of your vehicle in order to find any latent repair issues that need attention. This should be done before agreeing to fix or replace the transmission. The mechanic may come across something else that’s broken and requires fixing. If they do, get quotes for them, too.

It’s all about knowing precisely how much you’re expected to spend in order to get your vehicle up and running.

3. Does this vehicle still meet your needs?

You may have bought the car when you were still a bachelor. But now that you’re married with a couple of kids, the vehicle may not be the ideal one for you at the moment.

Find out if repairing the vehicle is worth it before selling it off and the price it commands. But set your mind on getting another vehicle that will capably meet you and your entire family’s needs. 

4. Is this vehicle well maintained?

The transmission is one of the components that easily go prematurely. In some cases, repairing the transmission will be worth it.

However, your maintenance procedure is key in this instance. If your car is not properly or well maintained, or you have poor driving habits, you may need to consider scrapping or selling off the vehicle.

But if you have always maintained the vehicle in pristine condition within and without, repairing the transmission may be worth it.

5. How Much Longer Do You Want or Intend to Keep This Vehicle?

Some vehicle owners drive their automobiles until they break down. This has significant financial benefits you should consider.

But if the vehicle has operated well all these years and only recently developed this transmission problem, ask how long you intend to keep this vehicle. Would you love to keep driving this vehicle for the next three years or more? If you answered in the affirmative, you should replace your transmission immediately.

You will get your money’s worth out of this brand-new vehicle transmission before selling off the vehicle.

If your automobile is still worth a lot of money, replace the transmission. You will still need to take this action whether or not you have decided to drive it or sell it off. No sane person will pay you a lot of money for a vehicle they can’t drive – since it has no transmission. Driving your vehicle is impossible without a transmission.

One primary advantage of replacing your transmission is the amount of money you will save. Another benefit is the automatic solving of every transmission problem you have encountered.

The Verdict?

As you already know, replacing a transmission is a costly repair job. When you have a major transmission issue, you should ask yourself this all-important question: “Is replacing the transmission worth it?”

Go through the reasons or questions highlighted above. This helps you make informed decisions after contemplating whether replacing the transmission is worth it.

5 Tips to Prevent Transmission Overheating

5 tips to prevent transmission overheating

Heat and transmissions are archenemies and will never go hand-in-hand. When transmission overheating occurs, it can cause multiple problems in your vehicle. This makes heat the principal cause of most premature transmission failures that car owners experience from time to time. 

Overheating transmissions account for about 90 percent of every automatic transmission failure recorded. It is so severe that you may need a total replacement, which will cost you a substantial amount of your hard-earned money. 

This is because it is primarily responsible for the following transmission issues:

  • Failed bearings
  • Cracked gears
  • Inoperable solenoids
  • Ruptured seals
  • Slipping transmission bands
  • Delayed clutch engagement

Whatever component is within the area where the transmission is located can suffer a breakage due to too much heat.

Causes of Transmission Overheating

Heat is a silent killer that has surreptitiously claimed the very active life of an innumerable number of transmissions. In many cases, excessive transmission heat goes unnoticed until something breaks, and it becomes too late to fix it. It may even be quietly damaging your vehicle each time you put it in gear.

The primary causes of excessive transmission heat include:

  • Low fluid levels
  • Solenoid problems
  • Fluid leaks
  • Old/burnt fluid

Other factors that contribute to the overheating of transmissions include:

  • Living in an area with a hot climate
  • Towing heavy loads/caravan with your vehicle
  • Always driving stop-and-go in heavy traffic, etc.

This is why it is essential to know what to do in order to reduce transmission temperature. This will protect your vehicle and save you lots of money in the end.

The Automatic Transmission Fluid

The automatic transmission fluid works efficiently to take away heat from the transmission. However, it also provides lubrication as well as the pressure required when changing gears. Expanding springs, spinning gears, and whirring turbines generate a lot of friction as they function.

This friction generates excessive heat, which, if left unattended, can cause varnishing, stress fractures, etc. The damage to the transmission’s internal components can be so severe that you will have to replace them.

This is why the automatic transmission fluid, which contains chemical additives, is formulated to absorb heat efficiently and flow through every moving component. 

The hot fluid transmits the heat from the transmission to the radiator, forcing it through a specialized cooling chamber. This chamber makes use of aluminum fins that efficiently remove the heat from the automatic transmission fluid.

How to Prevent Excessive Transmission Heat from Destroying Your Transmission

If your vehicle undergoes heavy use every day, you should be worried about your transmission overheating.

However, don’t fret: these tips will show you how you can prevent transmission overheating:

1. Install External Transmission Coolers

If your vehicle consistently hauls auto parts, other automobiles, wood, or heavy tools, you risk overheating your transmission. Your transmission will overheat due to the increased stress applied to your vehicle due to excess weight. This is more evident if your vehicle travels to and from hilly terrains.

Consider installing an external transmission cooler in your vehicle. External coolers are highly effective in keeping your transmission cool or at a regulated temperature, irrespective of the increased stress. External coolers will also work to minimize friction to the transmission, another cause of severe damage.

Visit the local transmission workshop to request or buy an external transmission cooler suitable for your vehicle. You can install the device on your own or get assistance from a professional mechanic.

2. Go Neutral from Time to Time

If you find yourself – in your vehicle, of course – sitting idly for a brief moment in traffic, shift your transmission into neutral and relax. Allow your vehicle to idle until the next moment when you have to move when traffic moves accordingly.

Allowing your vehicle to idle in neutral in heavy traffic, on railroad tracks, or while sitting at a red light significantly minimizes the strain on your vehicle’s transmission. This is your transmission’s chance to lose intensity by cooling down.

This action will prolong the lifespan of your transmission. Allowing your vehicle to idle in neutral when it is not in use will also reduce the amount of fuel your engine consumes. This means more money in your pocket as you save a lot of money as time goes on.

3. Check The Transmission Fluid Regularly

Make time to check your vehicle’s transmission fluid at least once a month. This makes it easier to identify burnt or worn-out dirty fluid or low-level fluid issues. These warning signs are easy to spot before they cause severe transmission issues that can utterly destroy your transmission.

4. Add A Deep Pan

Consider adding a deep pan if you experience excessive transmission heat. Deep pans allow users to add more fluid to vehicles. This, in turn, spreads out the heat, dissipating it and removing it completely from the transmission within a short period. 

Ensure you use only aluminum pans as they dissipate excessive transmission heat much faster than steel-constructed deep pans.

5. Change The Transmission Fluid On Time

Ensure you change your transmission fluid every 30,000 to 60,000 miles. You can do this easily on your own. But if you are not a DIY enthusiast, get your vehicle to the nearest transmission workshop in order to flush the fluid out of your vehicle.

However, if you live and drive your vehicle in a hot climate or find yourself hauling heavy loads from time to time or engaging in lots of stop-and-go traffic, it is advisable to change your transmission fluid every 15,000 to 20,000 miles.

This ensures your transmission fluid remains fresh at all times so that it can work efficiently by cooling the transmission.

Keepin’ it Cool

Overheating is one of the #1 causes of transmission failure. Research shows that excessive transmission heat accounts for up to 90 percent of automatic transmission failures. It is often undetectable until it is too late.

This is why it is crucial to do everything within your power to cool your transmission or prevent it from overheating. The tips shared in this post, if adhered to strictly, will prevent the occurrence of excessive transmission heat.

Keep Your Engine Purring with a Transmission Flush

Keep your engine purring with a transmission flush

Most vehicle owners usually focus on inspections, oil changes, battery replacements, tire care, brake service, and air filter checks. Indeed, every vehicle requires family care routines for optimal performance. However, one vital service consideration often overlooked by most car owners is transmission maintenance–specifically a transmission flush.

Most transmission issues often end in replacement, costing thousands of dollars. But you can perform preventative services such as transmission flushes to keep your transmission in top-notch condition.

Here’s what you should know about keeping your engine purring with a transmission flush.

But before then, let’s check out what a transmission does in your vehicle.

The Transmission

The transmission is one of the hardest-working and complex components in a vehicle’s engine. It is responsible for shifting gears within the motor and serves as the powerhouse of any vehicle.

Transmissions generally require proper maintenance, which includes constant lubrication via a transmission fluid. The latter protects the transmission from oxidative reactions as well as from the wear and tear that occurs due to the constant shifting and driving.

Why is a Transmission Flush Necessary?

The transmission fluid helps regulate temperature while keeping every component within the gear mechanism working seamlessly with zero friction.

However, since transmission fluids absorb heat when regulating the temperature within the gear system, the fluids start breaking down and burn over time. Waiting too long for a transmission flush may cause your transmission to deteriorate.

Transmission fluid flushes are necessary since they help prevent transmission issues. They work to ensure your vehicle is in peak condition at all times.

A transmission flush involves cleaning out old, dirty, and lackluster fluid from your transmission system and replacing it with fresh and clean transmission fluid. This process keeps your automobile healthy for a long time.

An ideal transmission flush should generally involve a transmission servicing such as:

  • Installing a brand-new air transmission filter
  • Installing a brand-new pan gasket
  • Fluid drain and removal from within the system, etc.

A transmission flush eliminates the need for costly transmission repair. It boosts overall engine performance while allowing your vehicle to shift gears smoothly and easily.

When is the Perfect Time for A Transmission Flush?

“But when exactly do I need a transmission fluid flush?” you may be asking. There is no one-fits-all answer for this because the measure of this service depends significantly on your driving patterns as well as your automobile.

Check the Owner’s Manual

However, you can get an insight by checking your owner’s manual. The manual should indicate the number of miles you need to cover in-between performing maintenance transmission flushes.

But if you can’t find any transmission flush guidelines in your owner’s manual, don’t fret. Your car engine could be one of the few that comes with a ‘lifetime’ transmission fluid, especially if the transmission is sealed.

Nevertheless, even sealed transmissions can permit contaminants into the workings of your vehicle and cause an issue or two, albeit at a much slower rate than traditional car engines.

Therefore, you may still require a transmission flush every few years. Your local mechanic or the official site of your vehicle manufacturer may share some insight.

Transmission Fluid Checks

You can also perform transmission fluid checks which is another accurate and incredibly easy way to determine if you need a transmission flush. 

Get a professional mechanic to look under your hood and check your transmission fluid’s overall status. You need to verify that the transmission fluid levels are not overly full but full enough.

You need to also confirm that the transmission fluid is not dirty or discolored by checking the fluid color. It must also be doing its job, including maintaining proper temperatures within the system.

However, you may not be capable of performing this examination or evaluation unless you are a certified engineer or mechanic. If you aren’t, experts highly recommend that you take your vehicle to the nearest local workshop.

Get the mechanic to help you check your vehicle’s transmission fluid. You can also make this request every time you change your oil. This helps you stay far ahead of necessary transmission flushes while ensuring your vehicle receives proper care.

The Benefits of a Transmission flush

The benefits of transmission fluid flushes cannot be overstated. In many cases, a vehicle’s transmission starts showing signs of wear and tear after every 30,000 miles.

Performing a transmission flush eliminates dirty fluid from the system and replaces it with clean fluids. The new, clean fluid re-lubricates the entire transmission system and keeps your engine purring. In other words, your vehicle runs much better as a result of this transmission service.

Here are the unique benefits of a transmission flush:

Prevents Overheating

Metal shavings and other particles from within the transmission eventually accumulate in your vehicle’s transmission fluid. If nothing is done, the transmission and fluid start heating up, causing the particles to burn and overheat every internal component within the transmission system.

This can cause system failures, resulting in costly repairs. A transmission flush prevents these issues.

Boosts Fuel Efficiency

An optimally-functioning transmission places less strain on the other mechanical components in the vehicle. Reducing the amount of friction that rotating and moving parts produce results in an increase in the amount of energy that is transferred to the wheels.

This significantly improves fuel economy and saves you money on gas down the road.

Enhances Gear Operation

An overheating transmission turns the transmission fluid into a gooey, thick sludge. This development of clogged gears makes it difficult to shift between speeds.

A timely transmission flush eliminates or prevents this condition and improves gear operation.

Take Care of Your Transmission

Transmissions are an incredibly large part of the movement of any vehicle. If your transmission fails to function, your vehicle goes nowhere.

You can ensure the continuous functioning of your transmission by performing a transmission flush from time to time. A transmission flush helps prevent overheating, improves fuel efficiency, and enhances gear operation, among several other benefits.

Get a professional mechanic to check your transmission today to determine if you need a transmission flush. It could save you the thousands of dollars required to repair or replace a broken-down transmission.

Transmission Fluid Color: What Do They Mean?

Transmission fluid color: What do they mean?

Do you know how revealing transmission fluid color is? It can help diagnose transmission issues while showing the overall health of your vehicle’s transmission.

The color of your car’s clean and fresh transmission fluid is usually bright red for a reason. But over time, the bright red color changes to maroon and brown. Should you be very concerned when this happens? This article will reveal the answer you need.

The Importance of Transmission Fluid

The transmission of your vehicle is highly essential in getting it into motion. Although the engine is primarily responsible for creating power, the transmission’s job is to transmit that power to the wheels. 

The transmission requires adequate fluid to reduce the friction between gear sets, create pressure, clean internal components, and prevent overheating. The fluid helps protect every component within a transmission system and keeps it free from dirt.

Checking the Transmission Fluid Color

You can determine the color of your vehicle’s transmission fluid in your transaxle or transmission by following these steps:

  1. Open your car’s hood and locate the transmission dipstick
  2. Pull out the dipstick from the filler tube
  3. Determine the color of the fluid

Check the fluid at the end of the dipstick and try to determine its color. You can place some drops of the transmission fluid on a clean white sheet of paper to obtain a more accurate reading.

There is an automatic transmission fluid color chart that you can utilize. Match the color of the transmission fluid to the fluid color chart. This will give you an accurate explanation and what you need to do.

But first, let’s check out the various colors of transmission fluid that you may likely come across.

Transmission Fluid Color and What It Means


Most brand-new transmission fluids have this color. It shows the fluid is not contaminated or dirty. The see-through, viscous transmission fluid has not oxidized and can efficiently protect the transmission and facilitate shifting gears.

This implies that no action is required whatsoever when the transmission fluid still shows this color.


Your transmission fluid should never be pink. Transmission fluid with this color implies the presence of engine coolant or water. This diluted transmission fluid can easily damage your transmission.

Therefore, when you notice that the transmission fluid color is pink, take your vehicle to your local mechanic’s workshop. Get the fluid drained from your transmission with the assistance of a professional technician.


If the transmission fluid looks orange, it is still in good working condition. However, it is an indication that the fluid is getting older.

You don’t need to change it yet as long as you can see through the transmission fluid with its orange hue. You can still drive your vehicle around for some time – i.e., a few more days or weeks – before flushing out the transmission fluid and refilling the gear mechanism.

Light Brown

When your transmission fluid has a light brown hue, it also shows that it is getting older. The fluid may still be translucent and pose no danger to your transmission, meaning you don’t have to change it yet.

Light brown transmission fluid is not really a sign of problems. You can still drive your car a bit longer before changing the fluid.

Brown/Dark Brown

However, as soon as the hue of the transmission fluid in your vehicle turns brown or dark brown, you have to change it. This usually occurs after your vehicle must have done up to 30,000 miles.

Brown or dark brown transmission fluid is no longer translucent but opaque. You can no longer see through the transmission fluid anymore. It is oxidizing – i.e., the fluid is getting filled with air bubbles which prevent the transmission fluid from doing its job effectively – and is no longer viscous.

So, change it right away as soon as you notice that your transmission fluid has taken on this color.

Other Ways to Check the Condition of Your Transmission Fluid

There are other ways to determine the overall condition of your transmission fluid.

The Smell of the Transmission Fluid

You can smell the transmission fluid. If it has a burnt odor, it simply means that the fluid is completely oxidized and overheated

The outcome is that the fluid offers poor lubrication, increased heat, and friction. This may result in excessive wear and severe damage to seals and internal components.

In fact, in many instances, burnt and smelling transmission fluid already implies that the gear mechanism itself has suffered some internal damage. You need to change that transmission fluid as soon as possible and have the technician check out the overall condition of the transmission itself.

The Blotter Test

Place a few drops of the transmission fluid on a paper towel. Wait for about 30 seconds. If the fluid is light brown or red or spreads out across the paper towel, no further action is required. The transmission fluid is in excellent condition.

But if the transmission fluid does not spread across the paper towel or looks dark, it implies that it has completely oxidized. You will need a filter and fluid change or have to flush out the transmission fluid from your vehicle.

Consistency is Key

Your vehicle’s transmission fluid color is one of the best ways to determine the overall health of your vehicle. You may also consider its smell and consistency in order to buttress what you suspect.

Most transmission fluids are red, though it is also not uncommon to get some in yellow or even blue. As the transmission fluid ages, the color changes gradually.

Therefore, consider changing the transmission fluid when its color has become dark brown. By protecting your vehicle’s transmission via maintenance, you prolong the transmission’s life span. You also prevent expensive rebuilds or replacements.

Make sure you don’t settle for less than the best transmission fluid for your car for optimum performance.

Yes, A Transmission Fluid Change is Needed (And Here’s Why)

Yes, a transmission fluid change is needed

If you notice your transmission slipping or have difficulty shifting gears, it may be time for a transmission fluid change. Over time, the fluid can become dirty or low, causing problems with your car’s transmission. A transmission fluid change is a relatively simple and inexpensive maintenance task that can help keep your car in good working order.

What is a Transmission?

A transmission is a gearbox that connects the engine to the drive wheels of a vehicle. The purpose of the transmission is to transfer power from the engine to the drive wheels while also providing a means to change gears, depending on the speed and load. Transmission fluid helps to lubricate and cool the transmission while preventing overheating and other serious problems.

When performing maintenance on your transmission, one of the things you should do is a transmission fluid change in order to ensure that your vehicle’s transmission is not only adequately lubricated and cooled but to keep it running at its optimal performance. Additionally, here are some other reasons:

  • Keeps components lubricated
  • Provides cooling
  • Prevents oxidation
  • & much more!

How Often Should You Change Transmission Fluid?

Most carmakers recommend that you change your car’s transmission fluid every 30,000 to 60,000 miles. However, this interval may be shorter or longer depending on the make and model of your vehicle as well as your driving habits.

For example, a person who uses their vehicle for light driving may only need to get a transmission fluid change much later. In contrast, a person who is constantly on the road traveling (e.g., heavy city driving) would likely need one sooner.

Additionally, deciding when to get your vehicle’s transmission fluid changed can be dependent on if it’s automatic or manual. Different transmissions may fall on different schedules for maintenance.

How to Check a Car’s Transmission Fluid Levels

To check your car’s transmission fluid levels, start by finding the dipstick. Typically, it will be located near the front of the engine on the driver’s side. Once you’ve found it, pull it out and wipe it off with a clean cloth or paper towel.

Then, place the dipstick all the way back into the transmission and pull it out again. Look closely to see where the fluid level is on the dipstick. If it’s below the “full” line, add more transmission fluid until it reaches that point. Finally, replace the dipstick and screw the cap back on.

When observing the transmission fluid, make sure to look at the color. Your transmission fluid should be bright red, while a darker color indicates that it’s time for a transmission fluid change. Sometimes you might find the fluid to be dirty or contain debris particles. This is another sign that your car needs new fluid.

When finished, take your car for a spin around the block to see if the gears are shifting correctly and to make sure the vehicle is running as intended.

Warning: Always check to ensure the engine and other components have cooled down before working on your car!

It’s advised to check transmission fluid levels while the emergency brake is set and the vehicle is parked on an even surface at operating temperature for best results. Also, place a jack under the car to raise it up, which will allow you to work under the vehicle.

Which is Better? Flush or Drain?

A transmission flush is when all the fluid in the transmission is flushed out and replaced with new fluid. This is generally considered to be a more thorough way of changing the transmission fluid, as all the old fluid and any debris that may have collected in the system is completely removed.

A transmission drain is simply draining the fluid out of the transmission pan and then replacing it with new fluid. This will generally remove most of the old fluid, but there may still be some debris left in the system.

If unsure, it’s best to speak with a professional mechanic or read the owner’s manual to see what the manufacturer suggests for your vehicle type and model.

Types of Transmission Fluid

There are many different types of transmission fluid on the market, including automatic transmission fluid (ATF), continuously variable fluid (CVT), and manual transmission fluid (MTF). ATF is the most common type of transmission fluid, while MTF is typically used in manual transmissions. CVT fluid can often be found in modern vehicles with advanced technologies equipped.

Likewise, there are different blends available, such as synthetic. Although it costs more, synthetic transmission fluid has quickly become a popular choice amongst car enthusiasts due to it providing better performance.

The Benefits of a Transmission Fluid Change

By changing the fluid in your transmission, you’ll get a host of benefits. Not only will your car be overall healthier, but it will also gain a ton of other perks:

1. Improved transmission performance

2. Reduced wear and tear on transmission components

3. Extended transmission life

4. Improved fuel economy

5. Smoother shifting operation

6. Better fuel economy

Additives, Age, and Quality

Additives are chemicals that are added to transmission fluid to improve its performance. Age can affect the quality of transmission fluid, as it can break down over time and become less effective. Using high-quality transmission fluid can help extend the life of your transmission and improve its performance.

When choosing transmission fluid, always consider these factors. For example, with older vehicles, it might be best to use a mineral-based oil fluid.

Risking your transmission by putting the wrong type in can put a dent not just in your car but in your wallet too!

Fresh Fluid for Smooth Ridin’

There are many reasons to change your transmission fluid, especially if you haven’t done so in a while. Transmission fluid breaks down over time and can start to cause problems. Fresh transmission fluid can help prevent these problems and keep your car running smoothly. As mentioned earlier, when in doubt, always speak to a professional mechanic and read the owner’s manual.

8 Basic Automatic Transmission Maintenance Tips

8 basic automatic transmission maintenance tips

Transmission maintenance is important because it can help prevent future car problems, extend the life of your transmission, and improve your vehicle’s overall performance.

But wait, that’s not all! Transmission maintenance can help you avoid costly repairs, and you’ll be saving a lot of money long-term! Now, who doesn’t love saving money? We sure do!

Transmission Maintenance Tips You Need to Know

To keep your car happy and your wallet full, here are eight basic transmission maintenance tips.

1. Allow Your Engine to Warm Up

First, always let your engine warm-up for a few minutes before driving off.

If you don’t, your car will be running on cold transmission fluid, and the transmission itself will have to work harder to do its job. It’s not good for your transmission to be placed under this type of stress, especially during the winter months when it’s freezing outside.

You should also avoid accelerating too fast or too hard until the transmission has had a chance to properly warm itself up. The time it takes a transmission to warm up can be anywhere between 5 to 20 minutes. However, if you have a newer car, your engine may only need a mere 30 seconds.

2. Be Wary of Driving on Spares or Mismatched Tires

Avoid driving on a spare, small, or mismatched tire for a long period of time. Driving under these conditions can cause premature wear on the transmission and jeopardize the safety of yourself and other passengers sharing the road.

If you have a flat tire, it’s crucial to replace it as soon as possible. However, sometimes this isn’t always possible right away for many reasons (e.g., cannot afford to or the local tire shop is closed). If you can’t replace the flat tire right away, allow your car to sit in a safe place until you can get a permanent tire.

3. Annual Transmission Inspections

As part of your transmission maintenance, it’s wise to have your transmission inspected by a professional mechanic for leaks, creaks, and other potential ongoing issues on an annual basis (one year). This will help to ensure that your transmission lasts for as long as possible.

Additionally, be sure to regularly check your transmission fluid level and top it off if necessary!

Remember: If you notice any strange noises or behaviors, don’t hesitate to get it checked out – it’ll save you a lot of money, worry, and stress down the road (no pun intended)!

4. Perform a Transmission Flush

As one of the most critical parts of a car, your transmission needs to be taken care of in order to keep your vehicle running smoothly. One way to take care of your transmission is to get it flushed regularly, which would be approximately once every year. More than likely, this type of transmission maintenance will be included as a part of a transmission inspection service.

A transmission flush is performed by flushing out the old fluid and replacing it with new fluid. This helps to keep the transmission clean and running smoothly. It also helps to prevent transmission problems later on.

If you’re not sure whether or not your transmission needs to be flushed, it’s always best to consult with a professional mechanic. A mechanic will be able to take a look at your car and let you know if a flush is required.

Furthermore, you can also read through your owner’s manual to know the recommended time for a transmission flush specific to your vehicle.

5. Picking the Right Transmission Fluid

Be sure to choose the correct transmission fluid for your vehicle. Placing the wrong type of fluid in your car can cause significant damage to the transmission, such as overheating, which can cause transmission failure. Again, it’s always best to read your owner’s manual or talk to a professional mechanic to ensure you’re using the right type.

There are several different types of transmission fluids, each designed for specific types of transmissions. For example, there are fluids specifically for automatic transmissions, as well as fluids for manual transmissions.

Once you’ve chosen the correct type of transmission fluid, it’s important to also select the right brand. Not all brands are the same, and some may be better suited for your car than others.

6. Regular Transmission Fluid Checks

A car transmission is a complex system made up of many different parts, and transmission fluid is essential to its proper function. Over time, transmission fluid eventually breaks down and becomes contaminated, which can lead to problems. That’s why it’s always important to regularly check your transmission fluid and change it as needed.

When checking the transmission fluid, there are several things to keep in mind:

  • Low Fluid: Indicates a possible leak.
  • Dark Fluid: Not normal; transmission fluid should be bright red.

7. Change the Transmission Filter

If your car has a transmission filter, get in the habit of changing it on a regular basis because it will help keep your transmission healthy. A lot of people forget about this filter, but it’s actually an essential part of your car’s transmission maintenance.

The process of changing your transmission filter may vary depending on your car. Generally, it’s recommended that a filter be changed out every 30,000 miles or 30 months.

8. Service the Cooling System

If your engine’s cooling system isn’t functioning correctly, it could create other issues for your transmission in time.

For example, if the coolant level gets too low, it can cause the engine to overheat. This can cause serious damage, including warping the cylinder head and damaging the transmission itself. In extreme cases or a worst-case scenario, it can even lead to a fire.

Practice Routine Transmission Maintenance Today

Transmission maintenance, such as getting the cooling system serviced or getting routine checks to identify potential leaks, is essential because it helps to ensure that your car’s transmission is working correctly and as intended. By keeping the transmission in good condition, you can avoid costly repairs and extend the life of your vehicle.

While typically performed by a qualified mechanic, you can also do some simple maintenance tasks at home to help keep your transmission in top condition for many years!

4L60E Transmission Swap Tips and Tricks

4L60E Transmission Swap Tips and Tricks

If you have questions about a 4L60E transmission swap and wondering what’s the best way to do so without any hitch, then this is your ultimate guide.

The 4L60E is a series of transmissions that were introduced for cars, trucks, and SUVs in 1993 by General Motors. And it was an improvement on the 4L60 transmissions earlier made–the improvement was the upgrade from hydraulics to electronically controlled transmissions. It is a perfect fit for retrofitting and street performance since they can be easily modified.

Its main characteristics are:

  • Electronic valve body with varied ratios for optimal performance
  • Four forward gears
  • Longitudinal mount
  • 60 relative torque rating of 360 lb-ft
  • 8.4 quartz fluid capacity
  • V6 and V8 engine compatibility

This transmission has had notable improvements and additional features over the years, and some of them include:

  • Pulse width modulated torque converter was added in 1995
  • Six-bolt tail shaft and modified downshift solenoid in 1996
  • Increased torque capacity in 2001

4L60E transmissions are efficient when you need to restore a vintage car or give a recent one an upgrade, especially when the use of these vehicles will be mostly on rough terrains or long road trips. Ordinarily, you can choose to use a manual gearbox, but with the fantastic capabilities of the 4L60E, it might just be your best shot.

What Vehicles are Suitable for the 4L60E Transmission?

It is important to note that there are vehicle configurations that are specific to the 4L60E transmissions; they include Buick Rainer, Cadillac, Chevrolet, GMC, Hummer, and Isuzu.

Comparing the 4L60 & 4L60E Transmissions

While the 4L60 is controlled with a TV cable, the 4L60E gets its own control from a computer. This difference can be sorted when the latter is placed in the position of the former; for this reason, all that is needed is for you to get a new transmission controller so that you can override its control mechanisms. Furthermore, another notable difference is that the 4L60 transmission requires the use of a custom bracket for the TV hook to fit in properly, which would not be a problem for the 4L60E transmissions since it would be controlled by a computer.  

In comparison, both transmissions have a few similarities–and topping this list is the fact that they are of the same length and have the same number of gears and gear ratios. Also, their bell housing bolt patterns are also similar.

Pros & Cons of 4L60E Transmissions

Before making a choice of whether to override your existing gear with a 4L60E transmission, you might want to take a break to ascertain if it is going to be a worthy investment. Let us delve into the pros and cons of this transmission.


  • Controllers of the 4L60E make it very easy; the establishment of exact shift points
  • Adjustment of shift firmness is also easily controlled
  • Full and firm control of all aspects of the shift
  • Changes can be easily made to the line pressure and shift points
  • Shift points can be adjusted from the interior, and this makes it less stressful
  • Calibration of the speedometer is super easy
  • Increased torque capacity
  • Fuel economy performance is solid
  • Super-fast transmission


As good as the 4L60E appears, there are certain disadvantages that have been identified. And, it is important to have an idea of these things before investing in them:

  • Expensive to set up because of the need for an external controller, which in this case is a laptop
  • Users must add a TPS input along with a carburetor
  • To spin the speedometer, you would need to add an adapter or run it electronically
  • Push-in clips often leak and might require constant replacement
  • Some users encounter issues with reverse clutches
  • Shifts are sometimes harsh and delayed while some completely stop working or get worn out

Users that have had previous issues with their 4L60E transmissions noted signs to be aware of when the transmission begins to fail so that it can be quickly managed. When you notice one or more of the following signs, please have an expert take a look at your vehicle:

  • A fluid leak occurs, and you occasionally get the ‘low fluid’ notification which in turn might make the transmission slip
  • The transmission might fail to move out of gear
  • Automatic transmission is affected, and the gear would neither upshift nor downshift

Handy 4L60E Transmission Swap Tips

Below are the tricks to successfully using 4L60E transmissions on vehicles and the difference in the process depending on the year of the vehicle:

4L60E year + Vehicle Year Required Processes
94 4L60E + 95 Vehicle There would be no need for any serious reprogramming and changes in mechanical or electrical configurations are not needed. The process is smooth and bolt ins are direct
94 4L60E+ 96 Vehicle The tail shaft housing and VSS of the vehicle would have to be installed on the 4L60E transmissions before it is bolted into the car. The 3-2 downshift is recommended for swapping too
96 4L60E+ 95 Vehicle The TCC lockup would have to be adjusted before the transmissions are done on the car as failure to do this might produce more heat during transmission as a result of the gas mileage that would have been affected
95 4L60E+ 94 Vehicle The tail shaft housing plus VSS has to be installed on the 4L60E before it is bolted into the car

Please note that the swap from a different transmission to the 4L60E requires the interchange of flexplates and torque converters which could be a herculean and confusing task for nonprofessionals.

Lastly, another important thing to note is your vehicle’s mile time before switching to a 4L60E so that you do not waste money on the switch and end up with a car on borrowed time.

5 Vehicles with Ford 4R70w Transmissions

Ford 4R70W Transmissions in a red mustang

Today, you are going to learn more about the magnificent Ford 4R70W transmissions, why they may be the ideal fit for your car, and also get to know the top 5 Ford vehicles that used the 4R70W transmission for better performance.

The 4R70W is no doubt one of the highly patronized and popular transmissions made by Ford. This transmission is a reviewed version of Ford’s AODE that was launched in 1993.

And ever since then, it has been widely used in a number of vehicles manufactured by Ford. That being said, the customized and revised version of this celebrated transmission is now commonly offered by different transmission manufacturers.

Historically, the first 4-speed Ford automatic transmission with AOD overdrive was launched in 1980, and another AODE transmission with electronic control features was released in 1992.

Subsequently, AODE was redesigned again in 1993, and this gave birth to the Ford 4R70W transmission with its enhanced strength, heavy-duty performance, take-off acceleration, powerful gear set as well as lower (first and second) gear ratios.

Without further ado, Ford used this powerful transmission in some of its cars before the company again revised the transmission design in 2004.

The Top 5 Vehicles That Used the Ford 4R70W Transmissions

Below are, however, the top five and the most popular Ford vehicles that used the 4R70w transmission for better acceleration and more:

  • Lincoln Mark VIII
  • Ford Expedition
  • Ford Mustang
  • Ford Crown Victoria
  • Lincoln Town Car

1. Lincoln Mark VIII

The Lincoln Mark VIII is arguably one of the first set of Ford cars to use the magnificent auto 4R70W transmission. And such is the reason why the car’s engine is one to beat till today.

This vehicle was first launched as Lincoln Mark VIII, and the name lasted for years as one of the fantastic vehicles in the automobile industry.

In addition, the 2-door coupe of Lincoln Mark VIII was initially launched in 1992 before it received a facelift a few years after. If there’s anything that would surprise you in this car, it is its gas mileage and standard engine performance.

More so, the recent version of this Lincoln Mark VIII Ford car has had an improved 4R70w transmission which enhanced its reliability and durability.

However, the company, in 1998, had discontinued producing Lincoln Mark VIII, with Lincoln LS enjoying all of its attributes now.

2. Ford Expedition

The Ford Expedition is another vehicle using the auto 4R70W transmission for its accelerated enhancement, gear ratio, strength, and general performance.

This Ford Expedition model was launched in 1996, and it is an SUV brand from the Ford company. This powerful car is designed similar to the Ford F-150 pickup, and it has several components that are alike.

In the same vein, the Ford Expedition underwent a major facelift sometime around 2003, and its auto 4R70W transmission component gained an improved version with control software.

This control software was specifically designed to ensure that the 4R70W transmission can have an automatic and better understanding of the towing requirements.

And last, the vehicle also makes use of an innovative device or computer logic designed in a manner to understand certain changes in road conditions.

3. Ford Mustang

Talking about the most popular vehicles manufactured by Ford, Mustang cannot be left unmentioned. It’s one of the grand touring luxury vehicles in those days.

The Ford Mustang came into lime-light in 1965, and it has since then witnessed several versions. The 6th generation of this Mustang, being a sports car for racing, is widely known for drag racing and stock car racing all over the world.

However, it was the 3rd and 4th versions of the Ford Mustang that came with the 4R70W transmission before it was subsequently replaced with Ford’s Tremec (T5) transmission in 2005 during the 5th generation production.

By and large, the present and available version, which is the 6th generation of the Ford Mustang, uses either the automatic Gretratag transmission or Ford’s 6-speed manual. 

4. Ford Crown Victoria

The Ford Crown Victoria was launched as a Sedan in 1992 by the Ford company, and the model was introduced as a luxury trim with a specific version of the half-vinyl roof.

When readers of certain ages hear Ford Crown Victoria, the first thing to come to mind is the mid-50s Cop cars. This vehicle is no doubt one of the most popular cars in those days.

The sedan made use of the Ford Panther platform, and almost all of its powertrain components and suspension were similar to Lincoln Town Car and Mercury Grand Marquis.

Specifically, this Sedan Victoria Crown was one of Ford’s first set of cars to use the AOD transmission prior to the launching of AODE transmission in the year 1993.

The Ford Victoria Crown of 1995 models had the AODE transmission too before it was subsequently replaced by the powerful 4R70W for better performance.

5. Lincoln Town Car

Last on the list of the top Ford vehicles that used the 4R70W transmission for better performance is the Lincoln Town car.

The car was manufactured and marketed by the Lincoln branch of Ford in 1981, and the production was ongoing not until 2011. Before its production was discontinued, Lincoln Town vehicle was one of Ford’s best-selling in the U.S. and Canada.

During the early stage of its production, the Lincoln Town car used the Ford’s AODE transmission before it was later replaced with 4R70W transmission for heavy-duty in 1998.

In 2002, the car also underwent a facelift when it graduated from the low gear 4R70W transmission to the latest and updated version of the 4R75W transmission.


At this juncture, you must know that the 4R70W transmission has over the years gained a positive reputation for itself as a result of its low gear ratios, heavy-duty performance, user-friendly budget price point, and more.

Several numbers of transmission manufacturing companies now offer the 4R70W to their prospective buyers that are willing to handle huge amounts of horsepower and torque manufactured by Ford engines.

Though not limited to the mentioned 5, the above discussed are the top 5 Ford vehicles that used the 4R70W transmission for better acceleration and heavy-duty performance.
